Description
Technical field
The present invention relates to automobile technical field, particularly a kind of cooling jet and controlling method thereof.
Background technique
Piston is arranged in reciprocating engine, and piston can move back and forth under oil pump applied pressure, carries out heat energy and mechanical transformation of energy.But piston can produce a large amount of heats in the process of motion, and temperature is higher, affects its proper motion, so, need to lower the temperature in the process of piston movement, its temperature is down to below safety temperature or safety temperature.
In prior art, spray cooling liquid by controlled cooling model nozzle to piston, piston is lowered the temperature.Concrete, cooling jet comprises nozzle body, plunger valve and Compress Spring.Nozzle body is column structure, the through hole of nozzle body is run through in direction nozzle body is provided with along the axis of parallel nozzle body, one end of through hole is injection end, plunger valve and Compress Spring are positioned at through hole, the telescopic direction of Compress Spring and the axis being parallel of through hole, one end of Compress Spring is fixedly connected with plunger valve, and the other end of Compress Spring is fixedly installed on the one end away from injection end on nozzle body.The side of nozzle body is provided with the traffic channel that is communicated with this through hole and nozzle body outside, and the liquid in through hole can be sprayed on piston through this traffic channel.When Compress Spring is uncompressed, near the bottom surface of injection end and nozzle body, the distance between the bottom surface of injection end is less than the distance near the bottom surface of injection end on traffic channel and through hole joint to nozzle body to plunger valve, now, traffic channel is not communicated with injection end.When using cooling jet to lower the temperature to piston, cooling liquid can be injected in through hole from injection end, controller oil pump applies pressure from injection end in through hole simultaneously, when oil pump equals cracking pressure to applied pressure in through hole, Compress Spring can shrink under the effect of the pressure, plunger valve is moved along the axis of nozzle body to the direction away from injection end, thus the distance between the bottom surface of injection end is greater than the distance near the bottom surface of injection end on traffic channel and through hole joint to nozzle body near the bottom surface of injection end and nozzle body to make plunger valve, now, traffic channel is communicated with injection end, cooling liquid can enter traffic channel from injection end, and then be ejected to piston from traffic channel, piston is lowered the temperature.Then oil pump is increased from injection end to applied pressure in through hole, the flow of the cooling liquid that cooling jet sprays is increased, until oil pump increases to working pressure to applied pressure in through hole, and keep oil pump to equal working pressure from injection end to applied pressure in through hole, continue to lower the temperature to piston.When oil pump equals cracking pressure to applied pressure in through hole, the flow of the cooling liquid that cooling jet sprays is turn-on flow rate.When oil pump equals working pressure from injection end to applied pressure in through hole, the flow of the cooling liquid that cooling jet sprays is working flow.
Because the temperature of the flow of cooling liquid that cooling jet sprays and piston is all relevant to oil pump applied pressure, but the flow of oil pump applied pressure on the cooling liquid that cooling jet sprays is different with the impact of the temperature on piston.When oil pump applied pressure equals working pressure, the flow of the cooling liquid of the temperature of piston being down to needed for safety temperature equals the working flow of cooling jet, but when oil pump applied pressure equals cracking pressure, the flow of the cooling liquid of the temperature of piston being down to needed for safety temperature is less than the turn-on flow rate of cooling jet, therefore, when oil pump applied pressure equals cracking pressure, the flow of the cooling liquid of the output terminal ejection of cooling jet is comparatively large, causes the waste of cooling liquid.
